The Minister deleted this species from the vulnerable category, effective from 15 May 2013

Advice to the Minister for Sustainability, Environment, Water, Population & Communities from the Threatened Species Scientific Committee (the Committee) on Amendment to the list of Threatened Species under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act)

1. Reason for Conservation Assessment by the Committee This advice follows assessment of new information on: Paradelma orientalis (Brigalow scaly-foot)

2. Summary of Species Details Taxonomy Conventionally accepted as Paradelma orientalis (Gunther, 1876) State Listing Status Listed as vulnerable under the Nature Conservation Act 1992. Description This lizard species has no forelimbs and hindlimbs reduced to scaly flaps (Cogger, 2000; Wilson and Swan, 2003). Scales are smooth, glossy with an opaque (milky) sheen, lead grey to greyish brown. The species has a black bar on the nape, with a cream to pale brown base of the head that darkens towards the rounded snout (Wilson and Swan, 2003; Wilson, 2005). A faint longitudinal striped pattern may be present, particularly on the sides (Cogger, 2000). Distribution Known from Queensland, it is likely that the species extends into New South Wales, though a record from that state has not been verified with a specimen (Hobson, 2005). Occurs in the bioregion in south-central Queensland (Cogger et al., 1993), the southern Desert Uplands bioregion and the bioregion (TSN, 2008). The range of this species extends from Nebo in the north, Boyne Island in the east, Wyaga (NSW) in the south and Ulcanbah Station and Idalia National Park in the west (Tremul, 2000; Kutt et al., 2003; TSN, 2008). Relevant Nocturnally active insectivore and arboreal acacia-sap feeder Biology/Ecology (Greer, 1989; Kutt et al., 2003; Tremul, 2000). Observed shelter sites include under logs, log piles, rock slabs, boulders, arboreal bark sheets, substrate bark sheets, forest litter, spinifex clumps and artificial habitat (e.g. iron sheets) (Shea, 1987; Schulz and Eyre, 1997; Tremul, 2000; DERM, 2009a, 2009b; Queensland Museum, 2009). Recorded in a range vegetation types including shrubland (acacia thickets, belah thickets, brigalow regrowth); woodland (Callitris, riparian eucalypt); grassy woodland; dry sclerophyll forest; closed forest (Allocasuarina); semi-evergreen vine thickets; grassland (including pasture and cultivated paddocks); disturbed roadside vegetation; and managed production forests (Shea, 1987; Schulz and Eyre, 1997; Wilson and Knowles, 1988; Tremul, 2000; Kutt et al., 2003; DERM, 2009a, 2009b; Queensland Museum 2009).

Threats Known There are no current known threats to this species. Potential Potential threats to this species include broad-scale and localised clearing leading to habitat fragmentation; dead wood and rock removal; inappropriate roadside vegetation management; heavy grazing; cane toads (Rhinella marinus), feral cats (Felis catus), pigs (Sus scrofa) and foxes (Vulpes vulpes) and inappropriate fire management (Richardson, 2008). The size and attractiveness of the Brigalow scaly-foot may lead to illegal collecting.

3. Public Consultation Notice of the proposed amendment was made available for public comment for 30 business days. Any comments received that are relevant to the survival of the species have been considered by the Committee.

4. How judged by the Committee in relation to the EPBC Act criteria and Regulations

Criterion 1: It has undergone, is suspected to have undergone or is likely to undergo in the immediate future a very severe, severe or substantial reduction in numbers

Not eligible

Criterion element Evidence Reduction in numbers Insufficient data – There are no direct measures of population trends or generation length. Vegetation clearing has been significant across the lizard’s extent of occurrence, however, the impact on the population numbers of this species is unknown.

Criterion 2: Its geographic distribution is precarious for the survival of the species and is very restricted, restricted or limited

Not eligible

Criterion element Evidence Geographic distribution Not limited – The estimated extent of occurrence is calculated at approximately 325 000 km2, with likely or known habitat AND within this area calculated at approximately 133 200 km2 (DERM, 2009a, 2009b, 2009c, 2009d; Queensland Museum, 2009). Regionally, the suitability of much of this habitat would depend on microhabitat features (distribution and number of shelter sites, soil variability at small scales) and land management practices such as fire, weed control and grazing. Geographic distribution No – Since 1990 a number of fauna survey records have precarious extended the species’ known range significantly (Schulz and Eyre 1997; Tremul 2000; Hobson 2003; Kutt et al. 2003; Augusteyn, 2007; DERM, 2009a, 2009b; Queensland

Paradelma orientalis (Brigalow scaly-foot) Listing Advice Page 2 of 5 The Minister deleted this species from the vulnerable category, effective from 15 May 2013

Museum, 2009) and it is likely future survey work will extend the distribution (Kutt et al., 2003). This species has been recorded in 16 Queensland national parks, and 21 state forest estates (Schulz and Eyre, 1997; Tremul, 2000; Hobson, 2003/ 2005; Augusteyn, 2007; DERM, 2009a, 2009b; Queensland Museum, 2009). None of these are specifically managed for this species; however a management profile of the species, with management guidelines to minimize the impact of forestry related activities on the lizard, is in operation (Fitzgerald, 1996).

Criterion 3: The estimated total number of mature individuals is very low, low or limited; and either (a) evidence suggests that the number will continue to decline at a very high, high or substantial rate; or (b) the number is likely to continue to decline and its geographic distribution is precarious for its survival

Not eligible

Criterion element Evidence Total no. of mature Insufficient data – There are no published quantitative data on individuals population size, structure or density. During a study on Boyne Island between 1989 and 1999, this species was considered AND fairly common (Tremul, 2000). Hobson (2003) considered it a cryptic species. Kutt et al. (2003) suggested this species was uncommon and rare at their fauna survey sites in the Desert Uplands and the northern end of the Brigalow Belt Bioregion, where over 7 500 pitfall trap nights and 350 hours of active searching found only five individuals. Wilson and Knowles (1988) reported it to be moderately abundant, particularly on sandstone ridges. Continued rate of decline No data OR Total no. of mature Insufficient data – There are no published quantitative data on individuals population size, structure or density.

Wilson and Knowles (1988) reported it to be moderately abundant, particularly on sandstone ridges. Continued decline likely Insufficient data – See Criterion 1 AND Geographic distribution No – See Criterion 2 precarious

Criterion 4: The estimated total number of mature individuals is extremely low, very low or low

Not eligible

Criterion element Evidence Total no. of mature Insufficient data – See Criterion 3 individuals

Criterion 5: Probability of extinction in the wild that is at least (a) 50% in the immediate future; or (b) 20% in the near future; or (c) 10% in the medium-term future

Not eligible

Criterion element Evidence Probability of extinction in No data the wild

5. Recommendations Based on available information on this species’ population size and geographic distribution, including no evidence of decline, the Committee notes that this species does not meet any of the required criteria for listing in any category. (i) The Committee recommends that the list referred to in section 178 of the EPBC Act be amended by deleting from the list in the vulnerable category: Paradelma orientalis
